Hints

Single piece transformation
When you have a slot down the middle and the two sides
are filled up except for one on one side and two on the other
and you get a blue piece, put it down the slot. When the bottom
reaches the holes, press [A] and the blue piece should turn.
The pieces should flash and turn into single pieces. Note: It
will erase blocks.
